c语言函数输入半径输出面积

#includemain(){\x09floatS(floatr);\x09floatr;\x09printf("inputr:");\x09scanf("%f",&r);\x09printf("圆面

#include#definepi3.141592653intmain(){doubler;printf("输入半径：\n");scanf("%lf",&r);printf("周长为：\n");pri

在输入半径的时候,语句改成scanf("%d",&r);不过你最好将半径定义成float型变量,格式的问题

#include"stdio.h"#definePI3.14159main(){floatr,V,S;printf("输入球体半径:");scanf("%f",&r);V=PI*4*r*r*r/3;S

voidmain(){floatr,s,l;floatpi=3.1415;printf("输入一个圆的半径:\n");scanf("%f",&r);if(

#include#definePI3.1415926\x05\x05voidmain()\x05{\x05doubler,s;scanf("%f",&r);s=PI*r*r;\x05printf("A

拿去慢慢研究吧#includeintmain(void){doubler=3.0,pi=3.14159,s;s=r*r*pi;printf("圆的面积为%lf",s);return0;}

1.楼主的x()和y()写的一样啊.2.在x()和y()中的定义intx1,x2;应该改为doublex1,x2;3.楼主对b*b-4*a*c
